' Application led June 20, 1914. Serial No. 846,264.

and State of Pennsylvania, have invented certain new and usefulImprovements in Braiding-Machines, of which the following is aspecification.

My invention relates to improvements in 1o braiding machines employing aset of spaced carriers adapted to carry a set of threadsupplyingdevices, a common carrier adapted to carry a, second set ofthread-supplying devices, means for supporting and' rotating said set ofcarriers' and said common carrier in opposite directions to each otherand for causing threads delivered from the said de,- vices carried bythe common carrier to move sinuously through the spaces between andaround the spaced carriers and the threadmachine shown and described inmy Letters Patent No. 1,144,716, dated June 29, 1915, to

which reference may be had.

rlfhe object of my present invention is the simplification of themechanism employed 3u for guiding the threads delivered from the.thread-supplying devices of the common' carrier sinuously through thespaces between and around the spaced carriers and the thread-supplyingdevices, carried thereby, as will be hereinafter fully ldescribed andparticularly claimed.

In the accompanying drawings, illustrating my invention: Figure 1, is aside elevation of my improved .braiding machine,

parts of the thread guiding arms for 'the upper thread-supplying devicesbeing 'broken away. Fig. 2, is a view of one o f the upperthread-supplying devices and its carrier detached from the machine. Fig.3,y isa development of a portion of the braid produced by my improved'machine.' Fig. 4, is a view, partly in section, of one of the threadAguiding devices for'the lower threadsupplying devices. Fig. 5, is afront elevation of the machine, partly in section, on line 4 4 of Figli.Fig. 6, is a horizontal section,.on line 6 6 of Fig. 5. Fig. 7is ahorizontal section, on line 7-7 of Fig. 5. Fig. 8, is a vertical sectionof the lower portion of the machine, on line 8-8 of Fig. 6. Fig. 9', isa plan ofthe outer and inner members between which the endless sinuouscourse is formed and which support the sectional track.

Referring to the drawings, 2 designates the base of the machine frame, 3a central standard rising fixedly from the 'base and 2O three outerstandards rising ixedly from the base and spaced around the centralstandard 3. Secured on the central standard 3 is a horizontal plate 18,and secured on the outer standards 20 is a horizontal plate 21, in thesame` horizontal plane with and surrounding the plate 18, but spacedtherefrom and providing an endless, sinuous course between the twoplates 18 and 21, as clearly shown in Fig. 9.

Rotatable on the central standard 3 below the plate 18is a carrier 8,carrying a set of thread-supplying devices 9 which `are mounted onsuitable brackets 10 secured to the carrier 8. The carrier 8 is rotatedby the main shaft 11 through co-acting bevel gear wheels 12 and 13securedto the/carrier 8 and shaft 1l, respectively. The main shaft 1l ismounted to turn in bearings 14 and 15 on the base 2; and the main shaftl1 is provided with a pulley 16 by means of which` it may be driven.

Secured on the outer portion of thecarrier 8 is a sectional, internalgear ring 29 which surrounds and coacts with the outer portions of smallgear-wheels 28l secured on the lower ends of a circular set of regularlyspaced vertical shafts `27 extending up through the plates 18 and 21 androtatable therein. The upper ends of the shafts 27 have small gearwheels 26 secured thereto and the inner portions of the gear wheels 26co-act with teeth formed on the outer portions of a circular set ofregularly-spaced carriers 23, carrying a set of thread-supplying devices24, corresponding in number with the devices of the set 9. The set ofcarriers 23 slide in and are supported and guided by a sectional annulartrack 22 which is formed bythe plates 18 and 21 and parts securedthereto and which is intersected by the sinuous course 35, as clearlyshown in Fig. 9. f

The threads from the lower thread-supplying devices 9 pass first throughguide eyes 19 on the bottom of the carrier 8 and then up throughvertical tubes 32 and from the tops of the tubes 32 to the braidingregion A. Each tube 32'is carried by the from the center of the machine,as the tube n moves through a slot 33 in the carrier 8 through which thetube 32 extends, andalso through the space between adjacent sections ofthe gearring 29. The tubes 32 also-eX- tend up through the sinuouscourse 35 to a position near the same level with the tops of the upperthread supplying devices 24; Each tube 32 is surrounded by ananti-friction roller 34 (see Fig. 4)' adapted to cooperate with thewalls -of the sinuous course 35.

The thread from each upper thread-supplying device 24 passes aroundvertical pins 37 on its carrier 23, thence to and through guide openingsina vertical pin 38 on its carrier 23 and from the upper end of the pin38 to the braiding region A.

The braided material B passes/from the braiding' region A up through aguide tube 36 secured to an angle arm 39 which is vertically adjustablein a bracket 40 carried b a pair of horizontal shafts 41 and 42 whicextend between and are supported by side standards 43 and 44 Xed on thebase 2, the

bracket 40 being ixedto the shaft 41, the

shaft 41 being vfixed to the standards, and the shaft 42 being rotatablein the standards.

. The braided material B passes up from the tube 36 to and around agrooved take-up wheel 45 mounted to turn loosely on the fixed lshaft 41between two `fixed collars thereon. The'take-up wheel 45 has a gearwheel 46 formed thereon which co-acts with a pinion 47 secured on therotatable shaft 42.

Secured on the outer end -of the shaft 42 isl a gear wheel 48 co-actingwith a gear wheel 49 on one end of a short shaft 50 mounted to rotate ina bearing 51 on the standard 44. The other end of the shaft 50 has aworm wheel 52 secured thereon which is driven by a'worm 53 secured onthe upper end of a vertical shaft 54 whichismounted to turn in a bearing55y on the standard 44. The lower end of the l'shaft 54 carries a beitelgear wheel 56 which co-acts with a similar wheel 57 on the main drivingshaft 11.

The operationof the machine is as follows: Power is applied to the mainshaft 11 to rotate yit in the direction of the arrows in Figs. 1, 5 and6 thereby rotating the carrier 8 in the direction of the arrows in Figs.

1 and 7 and rotating the take-up wheel 45, at a much slower speed, inthedirection of the arrows in Figs. 1 and 5, by the gearmg between thetake-up wheel 45 and the main shaft 11. As the carrier 8 is thus rotated5 in ythe direction of the-arrows in Figs. 5 and 6, the gearing betweenthe carrier 8 and the set of carriers 23 rotates the set of carriersfollow the sinuous course 35 by the rollers 34 engaging the wallsthereof. This 'operation causes the tubes 32 to intersect the path ofthe upper thread-supplying devices 24 and to move toward and from thecenter ofthe machine from the outside to the inside and from the insideto the outside of said path. This operation also causes the tubes 32 tomover.

between the adjacent sections of the gear ring 29 so that thetubes 32may pass around the outside of the shafts 27 supported by the plate 18and around the inside of the shafts 27 supported by the plate 21, thisbeing an important feature of my invention.

The gear wheels 26 are.so related to the teeth on the carriers 23 thatbefore the teeth of a carrier 2,3 leave a gear wheel 26 they are engagedby the next adjacent gear wheel 26, so thatthe carriers are alwaysmaintained equally spaced from each other while being driven.

The tubes 32 move around the machine with the,` devices 9 in theopposite direction to the devices 24, andthe timing of the movementof'each tube 32 with respect to the movement. of the devices 24and theircarriers 23 is such' that each tube32 will pass between the devices 24and between their carriers 23, and around the outside and then aroundtheinside of two adjacent devices 24 and their carriers 23 in alternatesuccession, and between each succeeding two adjacent devices 24 whichwere passed around by each tubes precedingv tube, thus causing the itubes 32 to interweave the threads from the devices 9 between and aroundthe devices 24 yand the threads delivered therefrom for the productionof the braid illustrated in Fig.

3. in which each thread passes over and under two threads-in alternatesuccession'and between the two threads overand under which the nextadjacent thread passes. As rapidly as the braid B is formed, it is drawnup through the guiding tube 36 by the`take` upwheel 45 which also drawsthe threads from the thread-supplying devices 9 and 24,

during, the weaving of the braid.

I claim:
